Missing medals in the barracks screen

[Paul Riley]

After a rather nasty crash tonight I was forced to begin patrol 3 again.The crash seems linked to saving my game last night submerged and in close proximity to a sinking ship.Anyway that aside I went into the barracks screen to check everyone was set up to my liking when I noticed all their u-boat clasps had disappeared.I distinctly remember after patrol 2 getting 6 uboat clasps,and had my watch and watch officer plus my chief recieve them.
My question is,have they gone for good,and why?,or has the game saved them for me for some reason ready to use after patrol 3?

Its not been a good night for me tonight has it.
